That's an untruth actually.
Take a granite color map, for example, which disperses a star-like pattern with parts
(dots) being scaled too
small to be seen (when AA is used especially, not sure at the moment if this does in
all cases) and then try an
increase in color value.  I think the previously invisible pixels will then appear.
You might be right though about it when non-AA rendering.
Same goes for objects too I think.  Seems I've encountered that before.
